【０００２】
【従来の技術】
図１０のユニット建物は、複数の下階建物ユニット１の上に、複数の上階建物ユニット２とバルコニーユニット３を搭載し、それらの上階建物ユニット２の上に屋根ユニット４を搭載したものである。このとき、上階建物ユニット２とバルコニーユニット３は、特開平7-76879号公報に記載の如くの、壁パネルの内面部に床パネルの外縁部を突合せ配置するとともに、床パネルを該ユニットの下端レベルより高位に設定してなるものとされ、下階天井高を確保可能としている。
【０００３】
【発明が解決しようとする課題】
然しながら、従来技術では、複数の下階建物ユニット１にまたがる下階天井空間の中に、上階建物ユニット２の壁パネル２Ａの下端部が垂れ壁状に突出し、下階天井空間の開放感が損なわれ、また、上階建物ユニット２の直下に設備箱物類が置けない。
【０００４】
本発明の課題は、壁パネルの内面部に床パネルの外縁部を突合せ配置し、床パネルをユニットの下端レベルより高位に設定した建物ユニットを用いながら、広く開放的な下階天井空間を形成し、設備箱物類の下階への設置自由度も向上することにある。
